robotlegs 2 Beta 4 and starling

I am searching a working example for the current beta 4 of
robotlegs2 that works with starling (I also want to throw some
spark-components in the mix, this is for a browser, not a mobile
application).
I have tried Alessandro Biancos starling-extensions https://github.com/alebianco/StarlingExtension-example
, but they do not work with robotlegs beta v4.
I also tried the robotlegs2-starling-viewmap by Jamie Owen https://github.com/jamieowen/robotlegs2-starling-viewmap,
but that does not seem to work either (the traces in the Mediator
of the example application never show up in the log).

So... is there a newer/better way to use starling with robotlegs
2 or do I have to port one of these examples?

I think, Alessandro, Jamie, and Vjekoslav, like many others who
wrote some extensions or examples, are waiting for rl2 to be
released - which may happen soon – before updating their
extensions or examples.

Thank you, Ondina, I rebuild and compiled SARS and the SARS
example (see
https://github.com/Vj3k0/robotlegs-bender-example-SARS-integration
) with RL2 v2.0.0b4 and it works without any changes (and with
"works" i mean compile and runs in a Browser without crashing for
at least 10 seconds... I have not tested the whole functionality
yet :-D ).
